【Abstract】 A chaotic circuit for truly random number generation is proposed.The chaotic system used in the circuit is implemented with the charge redistribution of capacitors.The prototype circuit is fabricated with a standard 0.8μm CMOS techno- logy process.The size of core is less than 4200μm2 and the power consumption is less than 1mW,which are better than that from most of present methods.更多还原
